A Boot Sector Virus Akugwira Ntchito Pakuyamba
Galimoto yovuta imakhala ndi magawo ambiri ndi magulu a zigawo, zomwe zingakhale zosiyana ndi chinthu chotchedwa kugawa. Kuti mupeze deta yonse yofalikira m'zigawo izi, chigawo cha boot chimagwira ntchito ngati Dewey Decimal system. Diski iliyonse imakhalanso ndi Boot Record (MBR) yomwe imafufuza ndi kuyendetsa yoyamba pa mafayilo onse oyenera opangira maofesi kuti athe kuyendetsa ntchito disk.
Pamene diski imawerengedwa, imayang'ana MBR, yomwe imapereka mphamvu ku gawo la boot, yomwe imapereka zidziwitso zokhudzana ndi zomwe zili pa diski ndi kumene zili. Gawo la boot limapatsanso chidziwitso chomwe chimadziwika mtundu ndi mawonekedwe a machitidwe omwe disk inapangidwira nawo.
Mwachiwonekere, chigawo cha boot kapena kachilombo ka MBR komwe kamalowa mu danga pa diskiyi imayika ntchito yonse ya diskyo pangozi.
Zindikirani : Vutolo ya boot sector ndi mtundu wa rootkit virus , ndipo mawu awa amagwiritsidwa ntchito mosiyana.
Ma Virus Odziwika a Boot Sector
Vuto loyamba la boot sector linapezedwa mu 1986. Ubongo Wopangidwa ndi Vuto, kachilomboka kanayambira ku Pakistan ndipo amagwiritsidwa ntchito mwakhama kwambiri, kutenga ma floppies 360 Kb.
Mwinamwake wopusa kwambiri pa tizilombo toyambitsa matendawa anali Michelangelo omwe adatulukira mu March 1992. Michelangelo anali MBR ndi boot sector infectrr ndi March 6th kulipira kuti patsogolo zovuta zoyendetsera magawo. Michelangelo ndiye kachilombo koyamba komwe kanapanga nkhani za mayiko.
Momwe Maselo Amagulu a Boot Akufalikira
Tizilombo toyambitsa matenda nthawi zambiri timafalitsa kudzera kunja, monga ma drive USB kapena zina monga CD kapena DVD. Izi zimachitika pamene osasamala amasiya zofalitsa zamtundu uliwonse. Pamene dongosolo likuyambanso, kachilomboka kamathamanga ndipo imathamanga mwamsanga ngati gawo la MBR. Kuchotsa zakunja zamtunduwu pamtundu uno sikuchotsa kachilomboka.
Njira inanso yomwe kachilombo ka HIV kamathandizira ndi kudzera mu imelo zomwe zili ndi boot virus code. Akayamba kutsegula, kachilomboka kamangogwiritsa ntchito kompyutayi ndipo ingathenso kugwiritsa ntchito mndandanda wa ojambulawo kuti atumize ma replicas okha kwa ena.
Zizindikiro za Boot Sector Virus
Zimakhala zovuta kuti mudziwe ngati mwapezeka ndi kachilombo ka HIV.Koma nthawi iliyonse, mukhoza kukhala ndi mavuto otha kupeza deta kapena deta yanu. Kompyutala yanu ikhoza kulephera kuyamba, ndi uthenga wolakwika "Boot disk yosavomerezeka" kapena "Wopanda dongosolo disk."
Kupewa Boot Sector Virus
Mukhoza kutenga njira zingapo kuti muteteze kachilombo ka root kapena boot sector.
- Kukhala tcheru : Mwachiwonekere, msinkhu woyambirira wa chitetezo pa tizilombo tonse timayang'anitsitsa: Musalowetse zofalitsa zosadziwika mu kompyuta yanu, ndipo khalani anzeru pa maulamuliro a ma imelo, zojambulidwa ndi zojambulidwa.
- Zida zotetezera Anti-Virus : Ngakhale zili zofunikira, komabe ndikuteteza pogwiritsira ntchito chida chowopsa chodziwidwa ndi kachilombo ka HIV. Mawindo a Windows 10 ndi Windows Defender, pomwe Mabaibulo oyambirira a Windows ali ndi Microsoft Security Essentials. Microsoft ikukulimbikitsani kusamukira ku Windows Defender ku mawindo akale a Windows. Kuonjezera apo, pali zida zambiri zaulere komanso zopatsa malire zomwe zilipo, kuphatikizapo a Malwarebytes ndi AdwCleaner omwe ndi amphamvu kwambiri McAfee ndi Norton, pakati pa ena. A
- Zindikirani : Musathamangitse zinthu ziwiri zoteteza kachilombo ka HIV nthawi yomweyo chifukwa wina akhoza kulepheretsa wina. Ngati mukufuna kugwiritsira ntchito mapulogalamu ambiri, samitsani wina asanayambe kuthamanga.
- Zosintha Zamakono : Sungani mapulogalamu anu osinthidwa chifukwa opanga mapulogalamu amapanga nthawi ndi nthawi makina ndi mapangidwe a mabowo otetezedwa omwe asokonezedwa ndi owononga ndi mavairasi.
- Zomangamanga : Kupanga zosamalitsa zokha basi koma kubwezeretsa boot disk kungakuthandizeni kubwezeretsanso ngati boot gawo kapena rootkit virus. Ngakhale iyi si njira yothandizira, izi ziyenera kuchitika musanalandire kachilomboka.
Kuchokera ku Boot Sector Virus
Chifukwa mavairasi a boot sewe amatha kufotokozera gawo la boot, akhoza kukhala ovuta kubwezera.
Choyamba, yesani kutsegula mu njira yotetezedwa yochotsedwa . Ngati mungathe kukhala otetezeka, mungathe kuyendetsa mapulogalamu anu odana ndi kachilombo pofuna kuyesa kuchotsa kachilomboka.
Windows Defender tsopano ikupatsanso "offline" version kuti idzakulolani inu kumasula ndi kuthamanga ngati sangathe kuchotsa kachilombo. Windows Defender Offline ndi yothandiza poyang'anira mavairasi a rootkit ndi boot sekha chifukwa amadziwa kompyuta yanu pamene Windows sichitha kuthamanga - kutanthauza kuti tizilombo sikuthamanga, mwina. Mukhoza kulumikiza mwachindunji izi mwa kupita ku Zimasintha , Kuonjezera & Kutetezera , ndiyeno Windows Defender . Sankhani Kusankha Osakanikirana .
Ngati palibe pulogalamu yotetezera kachilombo kamene imatha kuzindikira, kudzipatula kapena kusungira kachilombo koyambitsa matendawa, mungafunikire kukonzanso bwinobwino disk yanu ngati njira yomaliza.
Pachifukwa ichi, mudzakhala okondwa kuti munapanga zokopa!
